Model Introduces Hinged Rear Opening That Frees the Head Effortlessly and Launches an Innovative Proposal in Motorcycle Helmet Design
Roof introduced a model that changes the logic of helmet use and proposes a solution that breaks with patterns maintained for decades.
Although recent advancements have prioritized artificial intelligence, augmented reality, cameras, and intercom systems, the basic structure has changed little. The French manufacturer, active since 1993 and present in over 35 countries, seeks to change this scenario with the creation of the DJagger.
Differentiated Structure
The DJagger adopts a format that dispenses with the chin strap. Instead of the conventional fitting movement, the rear opens laterally, retracts, and elevates outward, creating ample space for entry or removal.

An engineer designs a solar plane to fly on Mars at an altitude of 1,000 meters and a speed of 300 km/h, covering 16,000 kilometers in a Martian year, 900 times the distance traveled by the Ingenuity helicopter in three years on the planet before experiencing a rotor failure, and NASA is already funding the feasibility study.

The operation resembles Iron Man’s helmet when observing the mechanism in action. According to Roof, it is a full-face helmet with an occipital opening and no chin strap, designed to allow for the removal of gloves and glasses during the process of putting on or taking off.

Comfort and Usability
The proposal includes improved acoustic insulation and adjustment. For those who wear glasses inside the helmet, the system offers a direct advantage, as the piece slides over the face and not over the head. The company emphasizes that this solution eases the work of emergency teams after falls, as it allows access to the face without requiring movements that could strain the motorcyclist’s neck.
Planned Features and Challenges
Roof intends to include a photochromic visor and Pinlock lens when the model advances to production, stages that depend on ECE 22.06 approval.
The project still raises questions about the functionality of the hinge and the need for recharges if the adjustment is electric.
There are concerns about the inclusion of moving parts and the impact on structural integrity, as well as the durability of the internal cords. The risk of mechanical failures and difficulties in opening the helmet also appear among the concerns.
Competitive Market and Next Steps
The sector is marked by strong loyalty from motorcyclists to brands like Arai and Bell, which may require significant effort from Roof. The DJagger remains in prototype phase, presented at EICMA this year, with no information on pricing or launch. There are rumors that tests are underway, but the company has not confirmed dates or values.
